The identification of Dogwood Anthracnose, caused by the fungus Discula destructiva, typically presents as leaf spots that are tan with purple borders. This appearance is characteristic of the disease, where the tan center indicates the area of tissue damage, and the purplish margin represents a distinct demarcation that can help distinguish it from other leaf spot diseases.

Understanding the visual symptoms associated with Dogwood Anthracnose is crucial for proper diagnosis and treatment. The other types of spots described do not match the typical presentation of this disease in dogwood trees. Identifying the right patterns on leaves is essential for effective management of the disease and prevention of its spread.
